Abstract: Taking Wuwei city, the evaluation index system of coupling coordination degree among TourismEconomyEnvironment is constructed. Secondly the weight of each index is calculated using SPSS 19.0. Thirdly, the coupling coordination development among TEE system from 2009 to 2015 in Wuwei city is analyzed. Lastly, the coupling coordinative degree of TEE from the year 2016 to 2020 by GM ( 1, 1) forecasting model is predicted．The results show that composite index development is jumping from 2009 to 2015 in Wuwei city. The speed of TEE system development is different.The coupling coordination degree is increasing year by year and the systematic coupled coordination types are gradually evolving from advanced tourism development as the main type into advanced economic development one. The ecological environment cannot afford the development of tourism and economy. In the following five years, the coupling coordination index is 0.5764, 0.6305, 0.6897, 0.7544 and 0.8252 respectively. The coupling coordinative degree of TEE will come into harmonious development.

摘要： 以武威市为对象，构建并测算旅游产业—区域经济—生态环境系统（TEE系统）耦合协调度评价指标体系及各指标权重，计算预测武威市的耦合协调度。研究表明：2009—2016年武威市TEE系统三子系统综合指数呈现跳跃式发展，且发展速度不同步，耦合协调度类型由旅游发展超前型转变为经济发展超前型，旅游和经济发展超出了生态环境的承载阈值。
